16. Control Strategy for Energy Efficient Fluid Power Actuators : Utilizing Individual Metering
Sammanfattning : This thesis presents a solution enabling lower losses in hydraulic actuator systems. A mobile fluid power system often contains several different actuators supplied with a single load sensing pump. One of the main advantages is the need of only one system pump. This makes the fluid power system compact and cost-effective. LÄS MER
17. A study on axially rotating pipe and swirling jet flows
Sammanfattning : The present study is an experimental and numerical investigation on rotating flows. A special facility has been built in order to produce a turbulent swirling jet generated by a fully developed rotating pipe flow and a Direct Numerical Simulation (DNS) code has been used to support and to complement the experimental data.

18. A new experimental setup for studies on wake flow instability and its control
Sammanfattning : A new experimental setup for studies on wake flow instability and its control, which has been designed and manufactured, is introduced and described. The main body is a dual-sided flat plate with an elliptic leading edge and a blunt trailing edge. LÄS MER
19. Numerical Investigation of Unsteady Crosswind Aerodynamics for Ground Vehicles
Sammanfattning : Ground vehicles are subjected to crosswind from various origins such as weather, topography of the ambient environment (land, forest, tunnels, high bushes...) or surrounding traffic. LÄS MER
20. Suspensions of finite-size rigid spheres in different flow cases
Sammanfattning : Dispersed multiphase flows occur in many biological, engineering and geophysical applications such asfluidized beds, soot particle dispersion and pyroclastic flows. Understanding the behavior of suspensionsis a very difficult task. LÄS MER
